Check Engine Light and Check Gear Box Light

I just purchased a 1998 Saab 900 SE Turbo convertible, and two faults just popped up: Check Gearbox and Check Engine. Car is running great: just had oil checked and transmission fluids checked. Ran it to AutoZone and came up with code P0741.
Unfortunately, in the area I live in: there are no Saab repair shops for hundreds of miles around: and it appears no local shops can read the error codes accurately.
Suggestions for what to do? Obvioulsy finding a mechanic that could read the codes correctly would be great: but logistics are a barrier.

WIS says that code is for lock up malfunction the issue reside in the wiring harness on the top of the box a good auto electrician with a modern diagnosis tool might be resolve your issue.

Ok, So I took my 1998 Saab 900 SE Turbo Convertible to an import mechanic to diagnose these exact fault codes: he told me it is the TCM.
He suggested I buy a new TCM and install myself to save money. Would you know where the TCM is located on this car?
